Mirella Gregori (born October 7, 1967) mysteriously disappeared from Rome in May 1983, about 40 days before the disappearance of Emanuela Orlandi, a citizen of Vatican City. Both vanishings are unsolved as of today.

During a visit of the Pope to a Rome parish, on December 15, 1985, Gregori’s mother recognized a man in the papal escort as the person who often came to pick up her daughter at the house.[4] The man was identified as Raoul Bonarelli.[5][6]
